How do i make a button that exits the game upon being pressed

i want a function that works in both standalone game application, and for a tab

It seems like you can close a tab with window.close().

i did see that in a previous thread, however closing a standalone application would be different and would probably take a more complex thing, that’s why i’m asking

Closing a standalone application is not really PlayCanvas related. I can imagine it depends on the operation system and the software you use, but I have no idea to be honest.

ahhh, that makes sense, is there any functions in the playcanvas coding system to allow ending of the process? that may work for both tabs and standalone applications

No, not as far as I know unfortunately.

Maybe consult the documentation of the tool you are using to create the standalone app. Maybe they provide a JavaScript method the exit the app
